3/4 cup sour cream

cool whip frozen whipped topping, thawed
Instructions
- In the microwave (I use my 8-cup Pyrex measuring cup for this) or on top of the stove (using a heavy-bottomed sauce pan) combine sugar, cornstarch, lemon zest, lemon juice, egg yolks, half and half and whipping cream (can use 2 cups half and half cream if desired and omit the whipping cream); whisk to combine.
- Microwave on HIGH until thick (removing about every minute to whisk/stir).
- Cook until thickened.
- Stir in butter; whisk until butter has melted and the mixture is smooth.
- Cool to almost room temperature, stirring every so often.
- Stir in sour cream until well blended.
- Divide evenly between baked tart shells.
- Top with a dollup of Cool Whip.
- Delicious!
